Abstract :
We propose and demonstrate an optical fiber-based scheme for GHz-frequency microwave pulse generation with full frequency and linear chirp reconfigurability. The scheme incorporates a balanced photodetection strategy to achieve dc-free microwave pulses with significantly improved noise figures.
